Description
Technical Field
The utility model relates to a suspension type truss and crane is put in tunnel belongs to engineering construction technical field.
Background
In engineering construction, tunnels are often required to be built to pass through obstacles such as mountains and existing buildings (structures), and in the process, due to the influences of factors such as complex geology and insufficient exploration, when the tunnels are built to pass through large karst caves, irregular karst cave cavities below tunnel lines need to be leveled and then foundations are built. Therefore, a slope-laying excavation method is usually adopted to form a foundation pit, and the earth and the dregs generated by forming the foundation pit are transported by installing a ground rail. However, the method needs to lay the ground rails, so that the excavation range and the occupied area in the tunnel are enlarged, and the muck generated by the foundation pit is generally placed in the ground rail transport trolley through a hand shouldering bar, so that the construction progress is influenced, and the efficiency is low.
